My version of nifi is an old one (1.9.2). I will pay more attention during my next upgrade. My nifi and my nifi-registry are both secured. I have only added the CN of my nifi app cert into authorizers.xml file (userGroupProvider and accessPolicyProvider). Mon, 10 Feb 2020 09:21:09 GMT JC_ROS 2020-02-10T09:21:09Z
